The 5900 ultra is noticeably slower with the special codepath and is horrendously slower under the default dx9 codepath;" edit: more links http://www.hardocp.com/article.html?art=NTE5 http://www.hardocp.com/article.html?art=NTE5LDM= 5x as much time optimizing NV3x path as we've spent optimizing generic DX9 path. ATI did not need it" http://www.hardocp.com/article.html?art=NTE5LDQ= "RUMOR": OEM DEAKS IS THE REASON FOR THESE BENCHMARK RESULTS. "REALITY: ATI's performance is the REASON WE HAVE an OEM deal" All you guys with 5900's that want to play HL2 better sell them and get a 9800p. Even with special optimizations for Nvidia FX cards, the performance isn't going to be good.. For a 400 dollar card too- wow.
